Abstract

A computerized tomography apparatus is disclosed which is able to selectively switch between a continuous scan mode and a single scan mode. Further, a scanogram may be achieved and displayed together with an adjustable line cursor, a couch carrying a subject being controlled to a position where a region of interest corresponds to the line cursor. The projection data acquisition can be interrupted and the couch can be moved back to the position corresponding to the last tomography image data.
